Starches are insoluble in water. Starch is used in cooking for thickening sauces. In industry, it is used in the manufacture of adhesives, paper, and textiles. The most promising new market for corn starches is as raw material for the production of industrial chemicals and plastics which are today made from petroleum feedstock. Wastewater effluent of starch production is characterized by high total suspended solids of high organic load. The Egyptian Starch, Yeast, and Detergents Company is one of most famous factories producing food starch. It is located in Alexandria. As its final wastewater effluent highly exceeds the permissible limits of total suspended solids [TSS] and chemical oxygen demand [COD] of Decree No. 44/2000 of Low No. 93/1962, the starch company established an anaerobic wastewater treatment plant [WWTP] since 2002. The present study aimed at evaluating the existing WWTP and the compliance of its final discharge with the regulatory limits for the disposal of final wastewater into public sewer. WWTP shows stable and controlled treatment unit with high treatment efficiency. It is fruitful to apply the same technology in treatment of end pipe industrial wastes having similar characteristics.
